Calculates the Barton-Choubey criterion for the given data and for the given level of stress (unit weight and depth).
Barton_Choubey(JRC, JCS, phi.r, unit.weight, depth)
JRC |
The Joint Roughness Coefficient (1-20) |
JCS |
The Joint Compressive Strength in MPa |
phi.r |
The residual friction angle of the rock |
unit.weight |
The unit weight of the rock in kN/m3 |
depth |
The depth, in meters, to which calculate the parameters |
A list with 3 tibbles: data (normal stress and shear stress), stress level point, and parameters (c and phi). All stress values are in MPa
